17 Claims, No Drawings I DETERGENT COMPOSITIONS BACKGROUND OF THE INVENTION The present invention relates to laundering compositions containing certain disubstituted polyol fabric softeners and certain polyamine anti-static agents. These materials can be used in the presence of detergents to soften fabrics concurrently with laundering.

Textile softeners and anti-static agents are used commercially to'improve the handle of fabrics and to reduce the annoyance of static electrical charges on fabric surfaces. A variety of cationic materials, such as the dimethyl-di(hydrogenated ta1low)ammonium halide salts, are widely used in the textile industry for this purpose. Similar cationic fabric softener and antistatic compositions are available for home use and usually consist of a solution or suspension of a cationic nitrogen compound similar to those used industrially. It has long been recognized that these cationic materials, although highly effectjvegvvhen properly applied, are incompatible with the anionic organic detergent compounds widely used in home laundering processes. For this reason, the user of such materials has heretofore been constrained to wait until the final rinse of the laundering process before adding the fabric softening and anti-static material to the laundering bath, or washing machines having specially designed fabric softener dispensers have had to be developed.

The aforementioned problem regarding the stepwise use of fabric softening agents in laundering operations would be obviated were fabric softening and anti-static agents which are compatible with modern built anionic detergent compositions available. Such agents could then be added to the laundering bath in conjunction with the detergent as a mixed composition to provide fabric cleansing, softening and anti-static benefits concurrently. Since this problem is widely recognized by the formulators of detergents and fabric softeners, a variety of materials have been suggested for use as detergent-compatible fabric softeners and anti-static agents. For example, U.S. Pat. No. 3,454,494 discloses a textile softener composition which is compatible with anionic detergents comprising an acid salt of a condensation product ofa fatty acid and an aliphatic polyfunctional amine co-condensed with a polyoxyalkylene compound. South African application 69/3923 discloses fabric softeners comprising certain N-2-hydroxy higher alkyl amines'said to be suitable for use as detergent-compatible fabric softeners. Polyalkyleneimine fabric softeners can be used in built anionic detergent compositions.

Nonionic fabric softeners are compatible with anionic detergents inasmuch as there are no functional groups in such compounds which are capable of interacting with the anionic portion of the detergents. For example, Canadian Patent No. 871,667 discloses the use of 1,2alkanediols as fabric softeners in conjunction with anionic detergents. However, these nonionic fabric softeners provide only marginal fabric softening benefits and are incapable of providing the anti-static benefits which are an important consideration to the user of such products.

U.S. Pat. No. 2,409,056 relates to non-alkylated polyamines and their use in soap to prevent rancidity. U.S. Pat. Nos. 2,296,226; 2,382,185; 2,185,480; and 2,272,489 describe the preparation of various alkylated and alkanoylated polyamines and suggest their use as fabric softeners in textile processing, but do not suggest the use of these materials in conjunction with anionic detergents and detergcncy builders.

To date, however, no truly effective fabric. softener and anti-static material which-is compatible with the widely used anionic detergent compounds and detergency builders has been suggested and the prior art materials disclosed for this purpose suffer from a variety of disadvantages. For example, the use of polyalkyleneimine softeners exclusively can lead to yellowing of some white'fabrics, 1,2-Diglycol based softeners do not provide substantial anti-static benefits. Many of the detergent-compatible softeners suggested in the art are excessively water-soluble, and good deposition on the fabrics is not achieved with such materials. Accordingly, it is an object of this invention to provide improved built laundry detergent compositions which possess significant fabric softening and anti-static properties A further object herein is to provide a process for simultaneously washing and softening fabrics while neutralizing static charge on said fabrics. These and other objects are obtained by the present invention as will become apparent from the following disclosure.

SUMMAR YOF THE INVENTION The present invention encompasses fabric softening laundry detergent compositions comprisingz-(l) from about 5 to about percent, preferably from about 5 to about 30 percent, by weight of a water-soluble organic detergent compound as hereinafter detailed; and (2) from about.2 to about 15 percent, preferably about 3.5 to about 10 percent, by weight of an a, w-disubstituted derivative of a non-cyclic, hygroscopic polyol, said derivative having the formula wherein x is an integer of at least 3, preferably 4, and each R is an alkyl or alkanoyl group containing at least 16, preferably 18 to 22, carbon atoms. In a preferred embodiment, the above-disclosed detergent composition also contains as a detergentand buildercompatible anti-static component from about 0.5 to about 1.5 percent by weight of a polyalkyleneimine compound containingthe moiety Especially preferred detergent compositions herein contain as an additional component about 85percent, preferably 25 to 75 percent by weight, of a watersoluble detergency builder salt. Optionally, a minor amount of laundry adjuncts such as optical brighteners, enzymes, perfumes and the like can be present in the compositions herein.

In addition, this invention encompasses a method of softening fabrics in aqueous laundering baths containing built organic detergent compositions, especially those containing anionic detergent compounds, comprising adding an new-disubstituted polyol of the type disclosed herein to said bath at a concentration of disubstituted polyol of at least about 20 ppm, preferably from about 75 ppm to about 300 ppm. Fabric softening is thereby provided concurrently with cleansing. In a preferred method, a polyalkyleneimine compound of the type disclosed above is concurrently added to the laundering bath at a concentration of polyalkyleneimine of at least about ppm, preferably ppm to about ppm, to provide an anti-static fabric finish concurrently with the cleansing and softening.

The foregoing benefits can also be achieved by adding the herein described disubstituted polyol and polyalkyleneimine materials to a substantially detergentfree aqueous laundry rinse bath at the concentrations noted above.

DETAILED DESCRIPTION OF THE INVENTION The disubstituted (a term which includes dialkylated and dialkanoylated)polyol softeners of this invention are derivatives of linear, hygroscopic polyols and have the general formula wherein .r is an integer of at least about 3, preferably 3 to 7, most preferably 4, and each R is an alkyl or alkanoyl group containing at least l6 carbon atoms. The above formula depicts the (Jaw-disubstituted polyols which are preferred herein.

The disubstituted polyols herein have two aspects of criticality in addition to the limitations on x and R noted above. First, they must have a substantially linear (i.e., noncyclic) configuration in the polyol portion of the molecule; substituted cyclic polyols (e.g., the Sorbitans) have been found not to be useful as fabric softeners. Apparently, the linear configuration of the disubstituted polyols herein allows them to interact more strongly with fabric surfaces than the cyclic polyols and provide the more complete surface coating necessary to impart softness.

Secondly, the disubstituted polyols herein must be derivatives of unsubstituted polyol compounds which are, themselves, hygroscopic, i.e., those which absorb 20 to 100 percent by weight of water on standing at a temperature of about 70F and a relative humidity of about 20 to 99 percent.

As noted'above, the arm-disubstituted polyols useful herein are limited to those which are derivatives of hygroscopic linearpolyols. There are a variety of such polyols (polyhydric alcohols; also termed alditols) there are various straight chain octitols and nonitols which can be prepared by controlled cleavage of complex natural sugars, followed by reduction of aldehyic and ketonic functionalities to alcohol groups.

It is to be understood that, of the foregoing linear polyhydric alcohols, only those which are hygroscopic are suitable for use in the preparation of the cam-disubstituted polyol fabric softeners herein. Thus, the requisite hygroscopic nature of the polyol provides a basis for selection of appropriate polyols which can be converted to di-substituted polyol fabric softeners in the manner hereinafter described. Preferred hygroscopic polyols for this purpose include sorbitol (most preferred), xylitol, and iditol.

The disubstituted (which includes dialkylated and dialkanoylated) derivatives of the foregoing polyols suitable for use as fabric softeners in the present invention are prepared by standard procedures well-known in the art. For example, the dialkylated polyols herein can be prepared by reacting 20 moles of an alkyl halide with 1 mole of polyol, preferably in the presence of a metal catalyst such as magnesium or copper, in the general manner of the Williamson ether synthesis. For this purpose, alkyl chlorides, bromides, and iodides having from about 16 to about 22 carbon atoms, preferably 18 to 22 carbon atoms, in their molecular structure are suitable. I

The preferred disubstituted polyols used herein are those wherein each R group is alkanoyl. These can be prepared in standard fashion by reacting 2 moles of a carboxylic acid or acid halide with 1 mole of a polyol. When acid halides are employed the reaction is preferably done in the presence of an organic base (e.g., pyridine, morpholine and the like) so that the reaction proceeds with the formation of the desired disubstituted polyol and the base hydrohalide. Acid chlorides, bromides, and iodides are suitable for this purpose; acid chlorides are preferred. Alternatively, lower alkyl esters of acids can be admixed at a mole ratio of 2:1 with the polyols and heated with the liberation of a lower alcohol and the formation of the disubstituted polyol. For this purpose, the methyl, ethyl and propyl esters of acids having an alkyl carbon chain of from about C to about C preferably about C to about C are suit able herein.

Disubstituted polyol materials prepared in the foregoing manner will have two substituent groups in the molecule; substitution can occur at any of the hydroxyl groups of the polyol. However, the major products of such reactions have been found to be disubstituted polyols wherein the a and 0) hydroxyl groups are substituted. It is to be understood that while the a,w-disubstituted polyols are the preferred fabric softeners herein, they may be contaminated with minor portions of the other disubstituted polyols. This in no way limits their use herein. However, the major proportion of the substituted polyols must be a,wdisubstituted.

Exemplary acids, esters acid halides and alkyl halides suitable for preparing the disubstituted polyols herein include palmitic acid and its acid halides, ethyl palmitate, stearic acid and its acid halides, ethyl stearate, eicosanoic acid and its acid halides, methyl eicosanate, docosanoic acid and its acid halides, and ethyl docosanate. Alkyl halides suitable herein include l-hexadecyl chloride, l-octadecyl bromide, l-eicosyl chloride, 1- docosyl bromide, l-octadecyl chloride, l-eicosyl iodide, l-octadecyl iodide and eicosyl chloride. Stearic acid and its acid chloride are preferred herein from an economic standpoint. Eicosanoic acid and docosanoic acid are preferred from the standpoint of preparing disubstituted polyols which exhibit optimum softening performance.

From the foregoing it can be seen that a variety of alkyl halides, organic acids and acid halides and esters having from about C to about C preferably from about C to about C carbon atoms in the alkyl or alkanoyl groups can be used with linear, hygroscopic polyols of the formula HOCH (CHOH),CH OH, wherein .r is an integer as defined above, to provide disubstituted polyols of the type used herein. Exemplary disubstituted polyols suitable for use in the present invention include the diesters: 1,6-distearoyl sorbitol, 1,6-bis-eicosanoyl sorbitol, 1,6-bis-docosanoyl sorbitol, l,5-distearoyl xylitol, 1,5-bis-eicosanoyl xylitol, 1,5- bis-docosanoyl xylitol, 1,6-distearoyl iditol, 1,6-biseicosanoyl iditol and 1,6-bis-docosanoyl iditol. Exemplary diether-type disubstituted polyols useful herein include: l,6-distearyl sorbitol, l,6-bis-eicosanyl sorbitol, 1,6-bis-docosanyl sorbitol, 1,5-bis-eicosanyl xylitol, 1,5-distearyl xylitol, 1,5-bis-docosanyl xylitol, 1,6- distc aryl iditol, 1,6-bis-eicosanyl iditol and l,6-bisdocosanyl iditol. The preferred cam-disubstituted polyol softeners herein are 1,6-distearoyl sorbitol, 1,6- bis-eicosanoyl sorbitol and l,6-bis-docosanoyl sorbitol. From a cost standpoint, the 1,6-distearoyl sorbitol is most preferred; From a performance standpoint, the 1,6-bis-eicosanoyl and 1,6-bis-docosanoyl sorbitols are preferred.

While the disubstituted polyols herein provide superior fabric softening benefits, they provide only marginal anti-static effects to the treated fabrics. Accordingly, in a preferred embodiment herein a detergentand builder-compatible compatible anti-static agent is used concurrently with the disubstituted polyol and the desired softening and antistatic benefits are thereby provided. The polyalkyleneimines having the hereinabove disclosed formula are employed herein as the 1 NCHgCHzN- wherein y is an integer greater than 1, usually about 2 to 100,000, and R represents hydrogen and alkyl or alkanoyl groups, as noted above. Branched chains occur along the polymeric backbone, and the relative proportions of primary, secondary and tertiary amino groups present in the polymer will vary, depending on the manner of preparation. The distribution of amino groups in a .typical polyethyleneimine is approximately as follows:

The polyethyleneimine can only be characterized in terms of molecular weight. Such polymers can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such .as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc.

Specific methods are described in U.S. Pat. Nos. 2,182,306; 3,033,746; 2,208,095; 2,806,836; and 2,553,696.

The alkylated and alkanoylated polyethyleneimines used herein are obtained by heating alkyl halides or organic acids or acid halides with the polyethyleneimine in the manner described in US. Pat. Nos. 2,296,226; 2,272,489; and 2,185,480, incorporated herein by reference. Other polyalkyleneimines are prepared in like fashion. in the case of the alkanoylated polyalkyleneimines, the alkanoyl groups are attached to the polymer backbone by amide linkages. Various ratios of alkylating or alkanoylating agent to polyalkyleneimine backbone can be employed so that varying percentages of the nitrogen atoms are thereby substituted. Polyalkyleneimines having various percentages of the nitrogen functionalities substituted with alkyl or alkanoyl groups are designated hereinafter as 20 percent stearoylated polyethyleneimine, 50 percent docosylated polybutyleneimine," etc, according to the percentage of'nitrogen groups in the polymer which are substituted. The percentage nitrogen substitution can be determined, for example, by an examination of the proton magnetic resonance or the infrared spectrum of the polymer. The alkylated and alkanoylated polyalkyleneimines, having molecular weights in the range of about 200 to about 1 million, are useful herein. The

lower molecular weight, less highly substituted polyalk yleneimines of this group are substantially watersoluble while the higher molecular weight members are water-dispersible; both the water-soluble and waterdispersible polyalkyleneimines are suitable for the present use. Preferred herein are alkylated and alkanoylated polyalkyleneimines, especially polyethyleneimines, having a molecular weight in the range of about 600 to 100,000, wherein from about 10 to about percent of the nitrogen groups are alkylated or alkanoylated. Polyethyleneimine having a molecular weight range of about 200 to 2,000, most preferably 600 to 1,200, and which is from about 15 to about 40 percent stearoylated, most preferably 20 percent stearoylated, is especially preferred for use herein as the detergent compatible anti-static agent.

The cam-disubstituted polyol fabric softeners described above are simply admixed with the polyalkyleneimines and are employed with all manner of soap and organic detergent compounds in conjunction with all manner of detergency builder salts to provide the softening, cleansing and anti-static compositions of this invention. Surprisingly, although the disubstituted polyols and polyalkyleneimines compete for deposition on the fabric surface, a portion of both kinds of materials apparently deposits thereon to provide the desired softening and anti-static benefits concurrently. The following describes typical soaps, synthetic organic detergent compounds and builder salts suitable for use with the disubstituted polyol softeners of this inventon or with the combination of disubstituted polyols and polyalkyleneimines, but is not intended to be limiting thereof.

ORGANIC DETERGENTS The organic detergent compounds which can be utilized with the combination of detergentand soapcompatible oz,w-disubstituted polyols and polyalkyleneimines in the laundering compositions and processes encompassed by this invention include the following:

A. Anionic Soap and Non-Soap Synthetic Detergents This class of detergents includes ordinary alkali metal soaps such as the sodium, potassium, ammonium and alkanolammonium salts of higher fatty acids containing from about 8 to about 24 carbon atoms and preferably from about 10 to about carbon atoms. Suitable fatty acids can be obtained from natural sourcessuch as, for instance, plant or animal esters (e.g., palm oil, coconut oil, babassu oil, soybean oil, castor oil, tallow, whale and fish oils, grease, lard, and mixtures thereof). The fatty acids also can be synthetically prepared (e.g., by the oxidation of petroleum, or by hydrogenation of carbon monoxide by the Fischer-Tropsch process). Resin acids are suitable such as rosin and those resin in tall oil. Naphthenic acids are also suitable. Sodium and potassium soaps can be made by direct saponification of the fats and oils or by the neutralization of the free fatty acids which are prepared in a separate manufacturing process. Particularly useful are the sodium and potassium salts of the mixtures of fatty acids derived from coconut oil and tallow, i.e., sodium or potassium tallow and coconut soap.

This class of detergents also includes water-soluble salts, particularly the alkali 'metal salts, of organic sulfuric reaction products having in their molecular struc ture an alkyl substituent containing from about 8 to about 22 carbon atoms and a sulfonic acid or sulfuric acid ester moiety. (Included in the term alkyl is the alkyl portion of higher acyl substituent.) Examples of this group of synthetic detergents which form a part of the preferred built detergent compositions of the present invention are the sodium or potassium alkyl sulfates, especially those obtained by sulfating the higher alcohols (C C carbon atoms) produced by reducing the glycerides oftallow or coconut oil; sodium or potassium alkyl benzene sulfonates, in which the alkyl group contains from about 9 to about 15 carbon atoms in straight chain or branched chain configuration, e.g., those ofthe type described in US. Pat. Nos. 2,220,099 and 2,477,383 (especially valuable are linear straight chain alkyl benzene sulfonates in which the average of the alkyl groups is about 13 carbon atoms and commonly abbreviated as C LAS); sodium alkyl glyceryl ether sulfonates, especially those ethers of higher alcohols derived from tallow and coconut oil; sodium coconut oil fatty acid monoglyceride sulfonates and sulfates; sodium or potassium salts of sulfuric acid esters of the reaction product of 1 mole of a higher fatty alcohol (e.g. tallow or coconut oil alcohols) and about 1 to 6 moles of ethylene oxide; sodium or potassium salts of alkyl phenol ethylene oxide ether sulfate with about 1 to about l0 units of ethylene oxide per molecule and in which the alkyl radicals contain about 8 to about 12 carbon atoms.

Anionic phosphate surfactants are also useful in the present invention. These are surface active materials having substantial detergent capability in which the anionic solubilizing group connecting hydrophobic moieties in an oxy acid of phosphorus. The more common solubilizing groups, of course, are SO,H, SO H, and CO H. Alkyl phosphate esters such as (R- O) PO H and ROPO H in which R represents an alkyl chain containing from about 8 to about 20 carbon atoms are useful.

These esters can be modified by including in the molecule from one to about 40 alkylene oxide units, e.g.,- ethylene oxide units. Formulae for these modified phosphate anionic detergents are in which R represents an alkyl group containing from about 8 to 20 carbon atoms, or an alkylphenyl group in which the alkyl group contains from about 8 to 20 carbon atoms, and M represents a water-solublecation such as hydrogen, sodium, potassium, ammonium or substituted ammonium; and in which n is an integer from I to about 40.

Another class of suitable anionic organic detergents particularly useful in this invention includes salts of 2-acyloxyalkane-l-sulfonic acids. These salts have the formula where R is alkyl of about 9 to about 23 carbon atoms (forming with the two carbon atoms an alkane group); R is alkyl of l to about 8 carbon atoms; and M is a water-soluble cation.

The water-soluble cation, M, in the hereinbefore described structural formula can be, for example, an alkali metal cation (e.g., sodium, potassium, lithium), ammonium or substituted-ammonium cation. Specific examples of substituted ammonium cations include methyl-, dimethyl-a and trimethylammonium cations and quaternary ammonium cations such as tetramethyl-ammonium and dimethyl piperidinium cations and those derived from alkylamines such as ethylamine, di-

ethylamine, triethylamine, mixtures thereof, and the like.

Typical examples of the above-described B-acetoxy alkanesulfonates are described in the literature: Belgium Patent No. 650,323 discloses the preparation of certain 2-acyloxy alkanesulfonic acids. Similarly, U.S. Pat. Nos. 2,094,451 and 2,086,215 disclose certain salts of ,B-acetoxy alkanesulfonic acids. These patents are hereby incorporated by reference.

Another preferred class of anionic detergent compounds herein, both by virtue of superior cleaning properties and low sensitivity to water hardness (Ca-l-land Mg-l-lions) are the alkylated B-sulfocarboxylates, containing about to about 23 carbon atoms, and having the formula wherein R is C,, to C alkyl, M is a water-soluble cation as hereinbefore disclosed, preferably sodium ion, and R is short-chain alkyl, e.g., methyl, ethyl, propyl, and butyl.

These materials have the formula RO(C H,O),SO M wherein R is alkyl or alkenyl of about 10 to about 20 carbon atoms, x is l to 30, and M is a water-soluble cation as defined hereinbefore. The alkyl ether sulfates useful in the present invention are condensation products of ethylene oxide and monohydric alcohols having about 10 to about 20 carbon atoms. Preferably, R has 14 to 18 carbon atoms. The alcohols can be derived from fats, e.g., coconut oil or tallow, or can be synthetic. Lauryl alcohol and straight chain alcohols derived from tallow are preferred herein. Such alcohols are reacted with l to 30, and especially 6, molar proportins of ethylene oxide and the resulting mixture of molecular species, having, for example, an average of 6 moles of ethylene oxide per mole of alcohol, is sulfated and neutralized.

Specific examples of alkyl ether sulfates of the present invention are sodium coconut alkyl ethylene glycol ether sulfate; lithium tallow alkyl triethylene glycol ether sulfate; and sodium tallow alkyl hexaoxyethylene sulfate.

The alkyl ether sulfates of the present invention are known compounds and are described in U.S. Pat. No. 3,332,876, incorporated herein by reference.

Additional examples of anionic non-soap synthetic detergents which come within the terms of the present invention are the reaction product of fatty acids esteritied with isethionic acid and neutralized with sodium hydroxide where, for example, the fatty acids are derived from coconut oil; sodium or potassium salts of fatty acid amides of methyl tauride in which the fatty acids, for example, are derived from coconut oil. Other anionic synthetic detergents of this variety are set forth in U.S. Pat. Nos. 2,486,921; 2,486,922; and 2,396,278.

Additional examples of anionic, non-soap, synthetic detergents, which come within the terms of the present invention, are the compounds which contain two anionic functional groups. These are referred to as dianionic detergents. Suitable di-anionic detergents are the disulfonates, disulfates, or mixtures thereof which may be represented by the following formulae;

3)2 2. R( 4)2 2, N 3) O z, A

where R is an acyclic aliphatic hydrocarbyl group having 15 to 20 carbon 'atoms and M is a water-solubilizing cation, for example, the C to C disodium 1,2-

alkyldisulfates, C to C dipotassium-l,2-alkyldisulfonates or disulfates, disodium 1,9-hexadecyl disulfates, C to C2,, disodium-l,2-alkyldisulfonates, disodium 1,9-stearyldisulfates and 6,10- octadecyldisulfates.

The aliphatic portion of the disulfates or disulfonates is generally substantially linear, thereby imparting desirable biodegradable properties to the detergent compound.

The watersolubilizing cations include the customary cations known in the detergent art, i.e., the alkali metals, and the ammonium cations, as well as other metals in group 11A, 118, 111A, IVA and N8 of the Periodic Table except for boron. The preferred watersolubilizing cations are sodium or potassium. These dianionic detergents are more fully described in British Letters Patent No. 1,151,392.

Still other anionic synthetic detergents include the class designated as succinamates, This class includes such surface active agents as disodium N-octadecylsulfosuccinamate; tetrasodium N-( l,2-dicarboxyethyl)-N- octadecyl-sulfo-succinamate; diamyl ester of sodium sulfosuccinic acid; dihexyl ester of sodium sulfosuccinic acid; dioctyl esters of sodium sulfosuccinic acid.

Other suitable anionic detergents utilizable herein are olefin sulfonates having about 12 to about 24 carbon atoms. The term *olefin sulfonates" is used herein to mean compounds which can be produced by the sulfonate of a-olef1ns by means of uncomplexed sulfur trioxide, followed by neutralization of the acid reaction mixture in conditions such that any sultones which have been formed in the reaction are hydrolyzed to give the corresponding hydroxy-alkanesulfonates. The sulfur trioxide can be liquid or gaseous, and is usually, but not necessarily, diluted by inert diluents, for example by liquid S0 chlorinated hydrocarbons, etc., when used in the liquid form, or by air, nitrogen, gaseous S0 etc., when used in the gaseous form.

The a-olefins from which the olefin sulfonates are derived are mono-olefins having 12 to 24 carbon atoms, preferably 14 to 16 carbon atoms. Preferably, they are straight chain olefins. Examples of suitable l-olefins include l-dodecene; l-tetradecene; l-hexadecene; loctadecene; l-eicosene and l-tetracosene.

In addition to the true alkene sulfonates and a proportion of hydroxy-alkanesulfonates, the olefin sulfonates can contain minor amounts of other materials, such as alkene disulfonates depending upon the reaction conditions, proportion of reactants, the nature of the starting olefins and impurities in the olefin stock and side reactions during the sulfonate process.

A specific anionic detergent which has also been found excellent for use in the present invention is de-- scribed more fully in the U.S. Pat. No. 3,332,880, incorporated herein by reference.

B. Nonionic Synthetic Detergents Nonionic synthetic detergents may be broadly defined as compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature) with an organic hydrophobic compound, which may be aliphatic or alkyl aromatic in nature. The length ofthe hydrophilic or polyoxyalkylene radical which is condensed with any particular hydrophobic group can be readily adjusted to yield a water-soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements.

For example, a well known class of nonionic synthetic detergents is made available on the market under the trade name of Pluronic. These compounds are formed by condensing ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol. The hydrophobic portion of the molecule which, of course, exhibits water insolubility, has a molecular weight of from about 1500 to 1800. The addition of polyoxyethylene radicals to this hydrophobic portion tends to increase the water solubility of the molecule as a whole and the liquid character of the product is retained up to the point where polyoxyethylene content is about percent of the total weight of the condensation product. 1

Other suitable nonionic synthetic detergents include:

1. The polyethylene oxide condensates of alkyl phenols, e.g., the condensation products of alkyl phenols having an alkyl group containing from about 6 to 12 carbon atoms in either a straight chain or branched chain configuration, with ethylene oxide, the said ethylene oxide being present in amounts equal to 5 to 25 moles of ethylene oxide per mole of alkyl phenol. The alkyl substituent in such compounds may be derived from polymerized propylene, diisobutylene, octene, or nonene, for example.

2. Compounds derived from the condensation of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylene diamine. For example, compounds containing from about 40 to about percent polyoxyethylene by weight and having a molecular weight of from about 5,000 to about 1 1,000 resulting from the reaction of ethylene oxide groups with a hydrophobic base constituted of the reaction product of ethylene diamine and excess propylene oxide, said base having a molecular weight of the order of 2,500 to 3,000, are satisfactory.

3. The condensation product of aliphatic alcohols having from 8 to 22 carbon atoms, in either straight chain or branched chain configuration with ethylene oxide, e.g., a coconut alcohol-ethylene oxide condensate having from 5 to 30 moles of ethylene oxide per mole of coconut alcohol, the coconut alcohol fraction having from 10 to 14 carbon atoms.

4. Nonionic detergents include nonyl phenol condensed with about 10 to about 30 moles of ethylene oxide per mole of phenol;-the condensation products of coconut alcohol with an average of either about 5.5 or about 15 moles of ethylene oxide per mole of alcohol, and, the condensation product of about 15 moles of ethylene oxide with one mole of tridecanol.

Other examples include dodecylphenol condensed with 12 moles of ethylene oxide per mole of phenol; dinonylphenol condensed with 15 moles of ethylene oxide per mole of phenol; dodecyl mercaptan condensed with 10 moles of ethylene oxide per mole of mercaptan; bis-(N-2-hydroxyethyl)lauramide; nonyl phenol condensed with 20 moles of ethylene oxide per mole of nonyl phenol; myristyl alcohol condensed with 10 moles of ethylene oxide per mole of myristyl alcohol', lauramide condensed with 15 moles of ethylene oxide per mole of lauramide; and di-isooctylphenol condensed with 15 moles of ethylene oxide.
